although I've been told my brother and cousin were tossing me on a trampoline when I was a year old and my kneecap cracked but I don't remember that so it doesn't really count but apparently it was funny to hear my one-year-old self walk down the hallway with a cast

Cracked a floater rib on my rib cage. Fell 1 time while doing a dead run on uneven terrain about 10 years ago and landed oddly.

Cranial injury sustained while complying with the laws of Physics. Something about a body in motion staying in motion once something else has stopped being in motion. At age of two did some professional stunt work by flying through a car windshield from a seated position and landing along a railroad grade 100' away from reference point of car roll. Though a serendipitous event my wardrobe lady had the tremendous foresight to wrap me in a one-piece child insulation suit. Actor posing as a real doctor with a medical degree suggested uni-suit kept out enough infection to enable said subject to continue living. Thanks to youth and repressed memory I have no recall of the incident but do possess residue of several head stitches upstairs and is main reason I don't like or wear crew cut haircuts.

I've only ever broken my wrist. I think I was in grade five.
Two people at school were having a fight and I made a joke in an attempt to lighten the mood. But instead of laughing, one of them pushed me over. I landed on my hand at an angle and CRACK.

When I came back with my arm in a cast and sling the next day, she went pale as a sheet. She ended up getting suspended, and when she came back, she sincerely apologised to me.

There's no hard feelings between us at all, though.

(And before you ask, no, it wasn't an offensive joke aimed at her. It was just a random one a friend told me. She just got pissed off with me because I interrupted their argument.)

I've hairline fractures my wrist. I've also broken 3 knuckles at once punching the ground (dead serious). They weren't complete breaks though, I could still move the fingers slightly. I have a scar between two knuckles on my left hand to prove it. Why did I punch the ground? I got pissed cause I was riding an electric razor scooter and went flying after the wheel hit a pinecone and buckled (LOL). I've had a lot of crazy stuff happen to me but I've rarely broken bones and its strange. I'm an extremely heavy milk drinker though so maybe high calcium intake has something to do with it growing up. Seriously though, I've wrecked on my bike in more ways than I can remember (bmx freestyle bike) and the only thing I ever did on it was a hairline fracture to the wrist.

My little brother has had it a lot rougher then me, broke nearly a full set a ribs during an ATV crash sending him flying into a tree got airlifted to a hospital and nearly died if it weren't for oxygen treatments cause his lungs were impacted. Broke a knee on a trampoline, few others... I never did anything to him, we actually get a long pretty well.

I broke both the bones in my arm by testing my balance on a wooden beam, luckily the break was clean and the bones healed quickly. Don't really remember if it hurt, all I remember is repeating, "my arms broken" to a teacher.
